Yes, it is time for ELK stack, ELK stack is a combination of multiple solutions. These solutions are Elasticsearch, Logstash and Kibana (ELK).
The 3 solutions have been stacked on eachother and this makes the solution beautiful. ElasticSearch is a open source and distributed REStful JSON-based search engine. It is easy to setup and use.
The community behind ElasticSearch is also very active. In order to do something with the data, they use Logstash, this is a great ingest pipeline. On top of the pie, there is Kibana.
Kibana is a visualization tool which is very easy to install and use. This tool allows you to visualise multiple types of data flows, making it a beautiful SIEM if used and configured correctly.
